Bluebird and HOSP

Postby Mitch Booth » Tue May 21, 2019 6:30 pm

Is it possible for a bluebird and European house sparrow to nest or breed together? A friend of mine asked me to inspect his bluebird house. I found a HOSP egg and 4 nestlings that look like bluebirds but the nest looks like a mix between a tree swallow and HOSP. Feathers everywhere and the nestlings are just starting to get there feathers and they look awfully blue and I would swear they are bluebirds. I keep seeing a HOSP visit the nest but have yet to see a bluebird or TRES visit the nest?

I would check it again in a day or two. I wouldn't be surprised if it is a TS nest and the HOSP killed or injured the parents and has moved in and started laying eggs.
2020 (HOSP Count 6)
2019- 31 Pair over 100 fledged
2018- 15 pair last count 49 fledged
2017 3 SY pair nested, 12 eggs total, fledged 10. 4 additional SY's stayed all summer but never paired/nested.
2016 1 pair fledged 4
2015 Visitors
2014 Visitors
2013 Moved 6 miles away, 1 pair fledged 2.
2012 30 pair fledged 100.
2011 12 pair (11 that nested), 43 fledged.
2010 5 pair, 21 eggs, 16 hatched, 14 fledged.

hosp will also use feathers in their nest, their babies will look blueish before they have feathers. Once your positive it's sparrows you should dispose of the whole family

Yep they are definitely sparrows. I will dispose of the entire nest and place a trap in the bluebird house to eliminate either the female or male who ever visits next.

I was surprised how blue they looked prior to getting their feathers. It was definitely a sparrow egg and the nest certainly looked like a HOSP but I was surprised to see how blue the nestlings were!! I've watched closer now and it is definitely being visited by HOSP.

Thanks for the information.
